RARITAN, N.J., June 21, 2012 /PRNewswire/ -- Janssen Research & Development, LLC (Janssen R&D) announced today the U.S. Food and Drug Administration (FDA) issued a complete response letter regarding a supplemental New Drug Application (sNDA) for XARELTO® (rivaroxaban) for the reduction of the risk of secondary cardiovascular events in patients with acute coronary syndrome (ACS). Janssen is evaluating the complete response letter and will respond to the agency's questions.

"We are confident in the robust study results of the ATLAS ACS 2 TIMI 51 trial and the positive benefit-risk profile of rivaroxaban in patients with ACS. We will continue to work with the FDA to fully address their questions as quickly as possible," said Paul Burton, M.D., Ph.D., Vice President, Cardiovascular Franchise Medical Leader at Janssen R&D.

XARELTO® is approved for three clinical uses in the U.S.: to reduce the risk of blood clots in the legs and lungs of people who have just had knee replacement surgery, to reduce this risk in people who have just had hip replacement surgery, and to reduce the risk of both hemorrhagic and thrombotic strokes as well as other blood clots in people with atrial fibrillation not caused by a heart valve problem.

ACS is a complication of coronary heart disease, which is the leading cause of death in the U.S. and one of the most prevalent non-communicable diseases in the world. ACS occurs when a blood clot blocks a coronary artery, reducing blood supply to the heart. This disruption of blood flow can cause a heart attack, or unstable angina, a condition signifying that a heart attack may soon occur. Each year, an estimated 1.2 million patients in the U.S. are discharged from the hospital with a diagnosis of ACS.

The sNDA includes results from the pivotal Phase 3 ATLAS ACS 2 TIMI 51 (Anti-Xa Therapy to Lower cardiovascular events in Addition to aspirin with/without thienopyridine therapy in Subjects with Acute Coronary Syndrome) clinical trial of XARELTO® which were presented at the American Heart Association (AHA) annual Scientific Sessions in November 2011 and simultaneously published by New England Journal of Medicine.

About XARELTO® (rivaroxaban)

XARELTO® belongs to a group of medicines called anticoagulants, and works by blocking the blood clotting Factor Xa, thereby reducing the tendency to form clots. XARELTO® is approved for three uses: to reduce the risk of blood clots in the legs and lungs of people who have just had knee replacement surgery, to reduce this risk in people who have just had hip replacement surgery, and to reduce the risk of both hemorrhagic and thrombotic strokes as well as other blood clots in people with atrial fibrillation not caused by a heart valve problem. There is limited information on how XARELTO® compares to a medicine called warfarin in reducing the risk of stroke when the blood levels of warfarin are well-controlled. The blood levels of warfarin often vary in patients.

XARELTO® has the broadest profile of any of the newer oral anticoagulants either in market today or coming to the U.S. market in the foreseeable future, and is broadly available for more than 90% of commercial and Medicare health plan members. To date, more than 1.5 million patients have received XARELTO® worldwide and nearly 350,000 prescriptions have been written for XARELTO® in the U.S. alone.

The extensive program of clinical trials evaluating rivaroxaban makes the compound the most studied oral, Factor Xa inhibitor in the world today. There are five filings currently under review at the FDA. Rivaroxaban is being developed jointly by Janssen R&D and Bayer HealthCare. U.S. marketing rights for XARELTO® are held by Janssen Pharmaceuticals, Inc.

Important Safety Information

WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT XARELTO®?

For people taking XARELTO® for atrial fibrillation:

People with atrial fibrillation (an irregular heart beat) are at an increased risk of forming a blood clot in the heart, which can travel to the brain, causing a stroke, or to other parts of the body. XARELTO® lowers your chance of having a stroke by helping to prevent clots from forming. If you stop taking XARELTO®, you may have an increased risk of forming a clot in your blood.

Do not stop taking XARELTO® without talking to the doctor who prescribes it for you. Stopping XARELTO® increases your risk of having a stroke or forming blood clots in other parts of your body.

If you have to stop taking XARELTO®, your doctor may prescribe another blood thinner medicine to prevent a blood clot from forming.

For all people taking XARELTO®:

XARELTO® can cause bleeding which can be serious, and rarely may lead to death. This is because XARELTO® is a blood thinner that reduces blood clotting. While you take XARELTO® you are likely to bruise more easily and it may take longer for bleeding to stop.

You may have a higher risk of bleeding if you take XARELTO® and other medicines that increase your risk of bleeding including:

aspirin or aspirin containing products,

non-steroidal anti-inflammatory drugs (NSAIDs)

warfarin sodium (Coumadin®, Jantoven®)

any medicine that contains heparin

clopidogrel (Plavix®)

prasugrel (Effient®)

ticagrelor (Brilinta®)

Tell your doctor if you take any of these medicines. Ask your doctor or pharmacist if you are not sure if your medicine is one listed above.

Call your doctor or get medical help right away if you develop any of these signs or symptoms of bleeding:

tingling, numbness or muscle weakness, especially in your legs. This is particularly important if you had a procedure called spinal or epidural puncture as part of your anesthesia during surgery.

any unexpected bleeding, or bleeding that lasts a long time (such as nose bleeds that happen often, unusual bleeding from gums, or menstrual bleeding that is heavier than normal or vaginal bleeding)

bleeding that is severe or that you cannot control

red, pink or brown urine

bright red or black stools (look like tar)

cough up blood or blood clots

vomit blood or your vomit looks like "coffee grounds"

headaches, feeling dizzy or weak

pain, swelling, or new drainage at wound sites

HOW SHOULD I TAKE XARELTO®?

Your doctor may stop XARELTO® for a short time before any surgery, medical or dental procedure. Your doctor will tell you when to start taking XARELTO® again after your surgery or procedure.

Do not run out of XARELTO®. Refill your prescription for XARELTO® before you run out. When leaving the hospital following a hip or knee replacement, be sure that you will have XARELTO® available to avoid missing any doses.

If you miss a dose of XARELTO®, take it as soon as you remember on the same day.

If you take too much XARELTO®, go to the nearest hospital emergency room or call your doctor right away.
